Syllabus

This course teaches the fundamentals of statistics, that is, the ability to describe data samples and draw inferences about the populations from which they were drawn. It should also sharpen individual intuition about how to read data, interpret data, and judge others' claims about data.

Learning objectives. At the end of this course students should be able to:
• construct a data sample appropriate for a given question/hypothesis and understand biases that can be introduced through sampling
• select appropriate methods to analyze such samples to determine whether the hypothesized effects are statistically significant
• critically analyze the sampling methods and analysis of others (e.g. don't take what the popular press tries to feed you about the latest health-related finding -- be able to read the source study yourself)
• stop worrying and love the data

Prerequisites: none

Reading: There are two required textbooks:

• Se5 (5th edition) or Se6 (6th edition) Introductory Statistics for the Behavioral Sciences by Welkowitz, Ewen, and Cohen.
• Re1 (1st edition), Re2 (2nd edition) Introductory Statistics with R by Dalgaard -- can be downloaded through UofM library search for "Introductory Statistics with R"

We will be using R in class. R is a statistical programming language, and it is open source. You should bring a laptop to every class for hands-on in-class exercises. If you don't have one, please contact the instructor to arrange for a loaner laptop during classtime.
